Definitions

  • the invention relates to a liquid damper in the form of a toroidal, flexible hollow ring according to the preamble of the main claim.
  • a joint is also known (CH-PS 463 885), in which hollow rings can be designed as open or closed hoses and have a liquid or gaseous fluid as a lubricant in the interior, the two (outer and inner) parts of the hollow ring being in contact with one another issue. Finally, the hollow ring is fixed to the two parts to be fixed to one another at least at one point.
  • the invention has for its object to develop a guide bush according to the preamble of the main claim so that it can spring and dampen in addition to the leadership function.
  • a guiding function in the alignment of the rod or of the tube arranged concentrically thereto is effected.
  • the guidance can therefore also take place along an arbitrarily curved space curve by
  • the rod is rigidly attached to a machine part and another is guided along the same, which is attached to the rod.
  • Torsional vibrations between the rod and the tube are also largely damped, the hollow ring abutting the inner wall of the tube on the one hand and the outer wall of the rod on the other in a firm frictional engagement.
  • the guiding properties along a degree of freedom with the guide bushing designed according to the invention are practically frictionless.
  • an elastic hollow ring with an incompressible fluid or an elastic hollow ring with a compressible fluid is used and, moreover, the hollow ring is arranged in its working position sc such that it is not yet completely encompassed by the tube and rather is immersed in the tube during compression, then inherit If the hollow ring is correctly dimensioned when the hollow ring is pulled into the tube, the volume of the fluid contained therein or a hollow ring made of elastic plastic or compressions of the compressible fluid in the case of a hollow ring made of inelastic plastic. In any case, this causes a resilient spring force.
  • a two-part design with the invention is also known, wherein the hollow ring is designed to be open and slotted all around on the outside transversely to the axis of the rod and each partial tube has a flange. Each edge formed by the open hollow tube is fixed between the flange of each partial tube and a separate central ring by clamping, for example by screwing the parts together.
  • the same spring and damping characteristics can be achieved as in the closed torus, but at each part-tube, a flange and the M ittelring required. It is also possible to use only one partial tube and to form the other part of the hollow ring freely on the outside or in any case above a partial tube.
  • the initially empty toroidal hollow ring is mounted and then the fluid is supplied via the central ring or bores or the like made there, which can also serve as ventilation openings.
  • the pressure of the fluid is adjustable.
  • the guide bush drawn in cross section in FIG. 1 has a flexible hollow ring 5 with a fluid 6 located therein.
  • the hollow ring 5 extends more in the axial direction 7 than in the radial direction 8 of the overall toroidal hollow ring 5.
  • a rod 10 Arranged in the opening 9 of the hollow ring 5 is a rod 10 which takes up at least the free cross section of the opening 9 and is inserted through the opening 9. Parallel to its extension and concentrically to it, a tube 11 is provided, the free cross section of which, schematically designated by 12, corresponds at most to the area enclosed by the rod 10 inserted through the center of the hollow ring 5.
  • projections 13 and ribs 14, which limit the free cross section of the hollow ring 5, are provided in the cavity 13 of the hollow ring 5, so that the flow cross section 15 for the fluid 6 when the guide bush is in operation, i. when deflection according to direction arrow 16 is reduced while increasing the flow resistance for the fluid 6.
  • Figure 3 shows a hollow ring 20 which is divided transversely to the axis of the rod 10 on its outer side 21, wherein the tube 11 is also divided into two and each partial tube is provided with a circumferential flange 23, between which a central ring, generally designated 24, is arranged.
  • the central ring has two wedge-shaped inclined surfaces 25 arranged symmetrically to one another and tapering in a wedge shape on each flange 23.
  • the counter surfaces 26 on the flasnch 23 are designed accordingly.
  • the edges 27 of the hollow ring 21 are clamped between them.
  • the flange 23 and the middle piece 24 outside the clear cross-section of each partial tube 11, however, have bores 28 extending parallel to the rod 10, through which the clamping screws 29 are inserted and secured by nuts 30.
  • the center ring 24 has a cylindrical inner wall 31 inside, in which a circumferential groove 32, preferably semicircular in cross section, is formed as a damping body for an O-ring designated as 33, which has a narrow one between it and the inner wall of the hollow ring 20 Has slot for the fluid that can be filled through a fill opening 34 in the center ring 24.
